More Information

This information bulletin does not include all information about the Average System of Net Quantity Determination. It does not include information on tolerances for products which are not likely to be offered at the retail level of trade. It does not, for example, include information regarding tolerances for products sold by linear measure, dry measure or count. It also does not include information regarding the calculation of weighted averages using linear interpolation.
